Yin JH, Ho YC, Lin HS et al. On-Call Duty Effects on Sleep-State Physiological Stability in Male Medical Interns. PLoS One 2013;8(6): e65072 DOI: 10.1371/journal.pone.0065072
To investigate if sleep stability decreased in medical interns during on-call duty.
The medical interns had significantly reduced stable sleep, and displayed increased latency to the first epoch of stable sleep during the on-call night shift, compared to the pre-call and on-call duty-free nights.
This reliable ECG-based method provides a simple and objective means to evaluate sleep quality in medical staff performing shift work under stressful conditions.
